BRAND NEW COMPOUND! Not a slime. Not sand. Not a powder. Not cotton. But somehow, it feels like a mix of all of these satisfying things. A melding of molecules that are dry, it is definitely a “solid” but it behaves a bit like a liquid too.

BUTTER SLIME – The key is the addition of air dry clay (hot pink) https://snoopslimes.co/products/funfetti-cake
ICEE SLIME – Pronounced “icy,” it’s a clear glue-based slime with wet fake snow (SnoWonder) though not as much as you’d add to a cloud slime.
